The emir of Qatar has responded to criticisms of the country's preparations for the 2022 World Cup by insisting it will be a success.

Sheikh Tamim bin Hamad Al-Thani, who succeeded his father last year, has taken a personal interest in the delivery of a tournament that has been shrouded by claims of corruption and dangerous working conditions plus concerns over the extreme heat games will be played in should a summer schedule go ahead.

"People should understand that Qatar had the best bid and Qatar will provide one of the best World Cups in history," Sheikh Tamim said. "People don't want to accept that a small Arab, Muslim country can host a big event like this."

The International Trade Union Confederation say more than 1000 migrant worker have died on construction sites.

"Yes, it's true we had problems but we're solving the problems. We're enforcing the laws - it's not acceptable," Sheikh Tamim said. "There are many laws that have been changed."

The emir spoke in definitive terms about the air conditioning system being worked on to ensure all stadia remain at safe temperatures for players and spectators, if the tournament goes ahead in the summer.

"It's up to FIFA to decide the best time. We're ready for both," Sheikh Tamim added: "We've had this technology for 10 years now and it's working in one of our stadiums. One hundred per cent it will be working by 2022."
